GROWTH AND YIELD RESPONSE OF POTATO (SOLANUM TUBEROSUM L) TO ORGANIC AND
BLENDED FERTILIZERS
- Authors: Seid Hussen Muhie
  Abstract: ABSTRACT: Appropriate nutrition management of the potato crop is crucial during the entire growth period as part of
  a successful agronomic strategy. In places of mid and high altitude where present yields of potato (Solanum tuberosum
  L.) are less than 10 t ha-1, where production is severely hampered by inadequate soil fertility, Ethiopia has a significant
  potential to boost potato production and productivity. A field experiment was conducted to determine the effects of
  integrated application of blended NPS fertilizer and compost on growth, yield parameters and yield of potato (Solanum
  tuberosum L.), variety ‘Belete’ under irrigation at Efrata Gidim District, North Showa, Ethiopia in 2022 cropping season.
  The treatments consisted of four Nitrogen-Phosphorus-Sulfur (NPS) blended fertilizer levels (0, 50,100 and 150 kg ha-1) and
  three compost levels (0, 10 and 20 t ha-1). The experiment was laid out as a Randomized Complete Block Design (RCBD)
  in a factorial arrangement and replicated three times. Data were collected and statistically analyzed using SAS version 9.2
  software. The findings revealed that the highest marketable tuber number per plant (14.1), total tuber number per plant
  (17.6), marketable tuber yield (13.0 t ha-1) and total tuber yield (15.48 t ha-1) were obtained from combined application of
  150 kg ha-1 NPS blended fertilizer and 20 t ha-1 compost. The integrated application of nutrients might have benefited the
  crop to access the essential elements for growth and development. The result can be temporarily recommended for potato
  producers around the study areas and similar agroecologies.

EFFECT OF GROWTH REGULATORS ON THE FORMATION OF POTATO (SOLANUM TUBEROSUM
L.) MICRO-PLANTS IN VITRO
- Authors: Rita Asakaviciute
  Abstract: ABSTRACT: Effect of growth regulators IAR (indole-3-acetic acid) and kinetin (6-furfuryl aminopurine) on length and
  mass formation of micro-plants of different maturity table potatoes (Solanum tuberosum L.) varieties was evaluated. The
  varieties of different maturity group included were very early ‘VB Venta’, early ‘Goda’, medium early ‘VB Meda’ and very
  late ‘VB Aista’. Microplant explants were grown in modified MS nutrient medium with different concentrations of growth
  regulators.. The concentration of 1.75 ml/l of auxin resulted in significant increase in length and weight of the micro-plant
  with highest micro plant growth (10.03± 0.96 cm) and mass (0.218 ± 0.09 g) formation in var ‘VB Meda’ compared to least
  growth in VB Venta’ (6.2 ± 0.75 cm). Kinetin at concentration of 0.8 ml/l resulted in longest micro-plants formation by ‘VB
  Meda’ variety (9.03 ± 0.18 cm) and the smallest by ‘VB Venta’ (5.20 ± 0.15 cm) explants.

ADAPTIVE MODELS FOR DETERMINING CROPLAND SUITABILITY AND TOTAL HARVEST
PREDICTION FOR POTATO USING IOT
- Authors: rindra yusianto
  Abstract: ABSTRACT: Potatoes are Indonesia’s fourth largest food agro-industrial and leading horticultural commodities traded
  internationally. In 2021, the needs of the potato industry will only be met by 85.93%. This study aims to provide
  recommendations for adaptive models for increasing productivity based on the suitability of agricultural cropland and
  predicting total harvest using IoT. We modified the multi-thresholding method by installing an SHT15 sensor to measure
  temperature. We also installed rain gauge sensors and analyzed the spatial perspective. Using a drone quadcopter, we
  perform image processing and mapping to predict the total harvest. The research sample used a random of 12 grids in an
  agricultural area in Wonosobo, Indonesia. The results showed that the most suitable agricultural cropland was 11.05%, suitable
  was 22.9%, and cropland with several inhibiting factors was 62.01%. The most convenient location is at the coordinates 7°
  15’ 12.1” S latitude, 109° 55’ 27.5” E longitude in Kejajar, Wonosobo District. The results also showed an average harvest
  of 13.79 t ha-1. This model can predict an increase in yields with a production prediction of 72,765 t year-1 and an accuracy
  rate of 89.35%. In addition, to balance supply and demand, this model recommends an increase in production by 30% and
  fulfillment from other regions by 31%.

EVALUATION OF CONVENTIONAL AND ZERO TILLAGE FOR POTATO CULTIVATION IN RICE
– POTATO SEQUENCE
- Authors: shiv pratap singh
  Abstract: ABSTRACT: A field study was conducted at the research farm of ICAR-Central Potato Research Institute RS, Gwalior
  (M.P.) during Rabi 2020-21 with three levels of rice cuttings viz. ground level, at 30 cm height and 60 cm height; and
  three tillage practices viz. tuber zone tillage, tuber row zone tillage and normal tillage, replicated thrice. Highest tuber
  emergence count (98.3%) was recorded with ground level rice harvest + tuber row zone tillage. Rice harvest at 60 cm
  height + tuber row zone tillage recorded highest plant height (41.3 cm). Highest fresh haulm weight/plant was recorded
  with rice harvest at 30 cm height + normal tillage (173.7 g). Highest tuber yield/plant was recorded with rice harvest at
  30 cm height + normal tillage (144.9 g). Highest total number of tuber was recorded with ground level rice harvest +
  tuber row zone tillage (575.7 thousand/ha). Highest total yield of tuber was recorded with rice harvest at 30 cm height +
  normal tillage (16.5 t/ha) which was significantly higher than T3 but statistically same with all other treatments. Highest
  net return was recorded with rice harvest at 30 cm height + normal tillage (27.3 thousand/ha). Highest number (31.3%)
  and yield (28.9%) of green tuber was recorded with rice harvest at 30 cm height + tuber zone tillage. Overall, integrated
  management of soil including conservation tillage is essential to enhance the crop productivity, economic profitability,
  and environmental quality.

CHARACTERIZATION OF ANDIGENA ACCESSIONS FOR BIOTIC STRESS RESISTANCE USING
LINKED MOLECULAR MARKERS
- Authors: Salej Sood
  Abstract: ABSTRACT: In the current study, 72 andigena accessions were screened for resistance to late blight, viruses (PVY and
  PVX), and potato cyst nematodes (PCNs) using gene-based linked markers. R1 gene was only present in one accession,
  JEX-A/668. Whereas two accessions, JEX-A/459 and JEX-A/616, showed the presence of the R2 gene. The R3a gene was not
  present in any of the accessions. The R3b gene was also amplified in the JEX-A/42, JEX-A/107, and JEX-A/459 accessions.
  In PVY resistance screening, the YES3-3A marker was found in 50 accessions. In comparison, 40 accessions tested positive
  for the STM0003 marker, which indicates the presence of the Rysto gene, whereas 14 accessions tested positive for the
  RYSC3 marker. In 9 and 20 accessions, respectively, the markers 1Rx1 and 106Rx2, which were connected to the extreme
  resistance genes Rx1 and Rx2 for PVX resistance, were discovered. Both 1Rx1 and 106Rx2 markers were discovered in six
  accessions (JEX-A/232, JEX-A/267, JEX-A/638, JEX-A/683, JEX-A/1061, and JEX-A/1092). Globodera spp. resistance screening
  revealed that 17 out of 72 accessions tested positive for the marker TG689. None of the accessions was positive for the
  SPUD1636 marker. Furthermore, the expected-size bands for the GPA2-1 and GPA2-2 markers, 1120 and 452 bp, respectively,
  were found in 15 separate accessions. Both markers show the presence of the Gpa2 locus, which almost completely confers
  resistance to one or more pathotypes of G. pallida.

BIODIVERSITY OF WEEDS IN POTATO (SOLANUM TUBEROSUM) IN PANGALENGAN AND
CIKAJANG SUB-DISTRICTS OF INDONESIA
- Authors: Uum Umiyati
  Abstract: ABSTRACT: Potato is one of the horticulture crops with the highest economic worth and the steadiest market interests.
  Weeds can affect agricultural output through competition for nutrients and water, sunlight for photosynthesis, and growing
  space. This study attempts to comprehend the proliferation of weeds in potato cultivation in West Java's Potato Centers
  of Pangalengan and Cikajang Subdistricts. The study was done between December 2020 and February 2021 using survey
  and vegetation analysis techniques. The vegetative analysis demonstrates that the diversity of weeds in potato cropping
  in the Pangalengan and Cikarang Subdistricts led to precise results. Four kinds of grassy weeds, two sedges, and eight
  broadleaf weeds were discovered in potato cropping throughout the Pangalengan Subdistrict. Two species of grassy weeds,
  two species of sedges, and eleven species of broadleaf weeds were discovered in the potato cropping across the Cikarang
  Subdistrict, which contained a total of fifteen species. The weeds with the greatest SDR (Summed Dominance Ratio) values
  in these two regions were Cyperus rotundus and Eleusine indica. The species diversity index value (H'), which fell into
  the medium category, and the community coefficient index value (C), which has significant degrees of difference, also
  revealed differences in diversity.

IRRADIATED POTATOES IDENTIFICATION BY THERMOLUMINESCENCE AND SEED TUBERS
GROWTH ANALYSIS IN CASE OF LOW GAMMA DOSE AND LATE IRRADIATION
- Authors: Faycal Kharfi
  Abstract: ABSTRACT: In this work, irradiated DESIREE potato was successfully identified by thermoluminescence technique for
  gamma dose up-to 1500 Gy. Selected SPUNTA and DESIREE potato seed tubers were also cultivated after being irradiated
  with different gamma low doses, varying from 10 to 150 Gy. Effects of gamma irradiation on plant growth, sugar content,
  and yield were studied. The potato seed tubers were late irradiated three weeks before planting. The analysis of tuber’s
  progenies shows non-mutation in terms of eye colour, skin colour and texture for low doses below 25 Gy. The emergence
  percentage of the plants were optimal for the dose interval of 10-25 Gy. No emergence ability has occurred at 55 Gy and
  75 Gy and higher dose for SPUNTA and DESIREE, respectively. Irradiation with 10-25 Gy promoted tubers formation.
  There was no morphological growth enhancement at 25 Gy and higher dose, and no survival of the plants at 65 Gy and
  85 Gy and higher doses for SPUNTA and DESIREE, respectively. The effects of gamma radiation on irradiated but not
  planted tubers show that total sugars content increases from ~1.5% to ~3.5% for low doses and keeps constant for higher
  doses. The harvested tubers produced from irradiated planted seeds show a constant sugar content even dose changes and
  non-influence of the irradiation on total sugar consumption and production. This study indicates too that late irradiation
  with low dose below 25 Gy (10Gy) significantly increases leaves number (+~75%) and growth capability in terms of
  tuber’s weight (15-30%).

- Authors: Benojir Yasmin
  Abstract: The prime goal of the present study is to ascertain suitable strategies regarding the sustainable and effective
  growth of potato cultivation in Hugli district of West Bengal by examining the Strengths (S), Weaknesses (W), Opportunities
  (O) and Threats (T) of the system through a combination of SWOT analysis and Analytical Hierarchy Process. The result
  reveals that constant year round demand of potato (S5, 0.25) and increasing expenditure costs (W3, 0.25) are the most
  prioritized internal strength and weakness respectively. On the contrary, large scale employment generation (O6, 0.29) for the
  locals as well as the migrant laborers is the most prioritized external opportunity, whereas, oscillating nature of economic
  profitability (T2, 0.27) is the most prioritized external threat of potato cultivation in the area. The overall priority scores
  of SWOT analysis exhibits that steady demand of potato throughout the year (S5) possesses the most significant (9.7%)
  aspect among all the internal and external factors. In conclusion, appropriate strategies have been formulated by linking
  the most prioritized ‘strength-opportunity’ and ‘weakness-threat’ factors for future possibilities of the potato cultivation in
  Hugli district of West Bengal.

ECONOMIZED WATER VOLUME AND CONCENTRATION OF FUNGICIDE FOR MANAGEMENT OF
LATE BLIGHT OF POTATO IN SUBTROPICAL PLAINS OF INDIA
- Authors: Mehi Lal
  Abstract: The late blight disease caused by Phytophthora infestans (Mont) de Bary, is one of the most devastating disease of potato. Fungicides are indispensable for quick and effective management of late blight disease of potato. Economizing water volume and concentration of fungicides along with proper coverage of foliage are most important aspects for successful management of late blight disease. Most commonly, fungicide mancozeb 75 % WP was evaluated at four doses in different water volume during three consecutive years (2017-20). The results revealed that mancozeb @ 0.5 % (2.5 kg/500 L water/ha) had least average disease severity (25.28 %), followed by mancozeb @ 0.4 % (2.0 kg/500 L water/ha, 26.50 %) and mancozeb @ 0.3 % (1.5 kg/500 L water/ha, 26.33 %) against of 96.39 % in control. These treatments were found statistically at par with each other. The highest average tuber yield (34.35 t/ha) and B: C ratio (2.80) was recorded when mancozeb applied @ 0.5 % (2.5 kg/500 L water/ha) against tuber yield 28.14 t/ha & B:C ratio of 2.42 in control. It can be concluded that concentration of fungicides have much more importance along with proper coverage of plant foliage. Hence, the water volume of 500 L/ha is sufficient with battery operated knapsack sprayer.

EFFECT OF OF ORGANIC FERTILIZERS ON NUTRITIONAL AND PROCESSING QUALITY OF
POTATOES (Solanum tuberosum L.)
- Authors: Vedaste Ndungutse
  Abstract: The aim of this study was to determine the effect of different organic fertilizers on the nutritional and processing quality of potatoes. Composting of different materials was done using 12 forumulations and it lasted 6 months. These compost were used to grow potatoes, Kinigi variety, at the rate of 10 tonnes per hectare and control was used as well. Parameters analysed were moisture content, crude protein, crude ash, crude fibers, reducing sugars and total sugars uing standard methods. There was a significant different in parameters analysed of different treatment at P < 0.05. Mositure content ranged from 73.05 to 80.44%, proteain from 1.22 to 3.64%, ash from 0.17 to 2.12%, fiber from 3.04 to 4.08%. Analysis of sugars showed that reducing sugars ranged from 1.29 to 2.28% and total sugars from 2.22 to 2.94%. These potatoes are suitable for boiled and mashed products. However, due to high sugar content, they are not suitable for dehydrated and fried products. Controlling maturity and handling should be emphasized in order to reduce the amount of reducing sugars.

  EFFECT OF CLIMATE VARIABILITY ON POTATO YIELD UNDER DIFFERENT AGROCLIMATIC
  ZONES OF PUNJAB
  - Authors: Sarabjot Kaur Sandhu
    Abstract: A study was conducted to determine the role of meteorological parameters on year to year variability in potato
    yield in two different agroclimatic zones of Punjab viz. Central Zone (Ludhiana) and Western Zone (Bathinda) using last 17
    years (2003-04 to 2019-20) data. The meteorological data of different months from October to January was used to conduct
    this study. The meteorological data of October and November month did not show any significance for locations. Whereas,
    meteorological data of December and January month significantly influenced potato yield at both locations. Potato yield
    showed highly significant positive correlation with minimum temperature and evening relative humidity for both locations
    whereas yield showed significant negative correlation with sunshine hours at Ludhiana. After studying the deviation of
    meteorological parameters from respective normals during highest and lowest yield years and the correlation of meteorological
    parameters with potato yield it can be concluded that in the Punjab minimum temperature along with sunshine hours play
    a major role in determining the potato yield. Regression model based on maximum and minimum temperature, morning
    relative humidity and sunshine hours gave good results. Validation of the regression models for prediction of potato yield
    proved the efficiency of the targeted predictions at both locations.

    Authors: Sapna Bhardwaj Sapna
    Abstract: This study focuses on the application of the ARIMA time series model to forecast the future potato production
    in Himachal Pradesh based on past data from 1991-92 to 2019-20. The stationarity of the data has been checked using
    the augmented dickey Fuller test which showed that the data was non-stationary. Therefore, differencing up to the first
    order has been done to make it stationary. Based on various model selection criteria, the best-fitted model was ARIMA
    (0, 1, 1) which has been used for the forecast of the next five years i.e., from 2020-2024. From the forecasted figure, potato
    production will go from 29612.36 tons to 22543.08 tons in 2024 showing an increasing trend.

    Authors: Anshul Thakur
    Abstract: The most challenging insect-pests of the potato crop in Himachal Pradesh are white grubs. Their diversity
    tends to fluctuate, depending on altitude, geography, ecosystems, and other environmental variables. The survey on white
    grubs of potato was carried out in 19 locations from five districts of Himachal Pradesh during 2021-22. The altitude of
    these locations varied from 1378-3279m amsl. In total, 13 species of white grubs were collected feeding on roots and tubers
    of potato crop. Out of 13 species, 8 species have been identified as Brahmina crinicollis Burmeister, Brahmina coriacea
    (Hope), Brahmina flavosericea Brenske, Holotrichia longipennis Blanchard, Anomala rufiventris Redtenbacher, Melolontha
    furcicauda Ancey, Melolantha cuprescens Blanchard and Polyphylla sikkimensis Brenseke. We couldn’t rear four species till
    adult emergence and hence this species remained unidentified. The raster patterns of all 13 species have been described
    with suitable pictures.

  - ORGANIC POTATO PRODUCTION: A STEP TOWARDS SUSTAINABLE AGRICULTURE (LIFE
    CYCLE ASSESSMENT BASED STUDY)
    
    Authors: Arvind Bharadwaj
    Abstract: Potato as staple vegetable has a significant influence towards the global target of food security. However,
    its production is also correlated to environmental burden via the processes like fertilization, crop protection and the
    production of electricity for irrigation. Although organic production is known to reduce the impacts of fertilizer as well
    as other agro-chemicals due to their non-usage, there is a need to assess its overall impact in the light of its related
    processes with respect to transportation of manure and higher water requirements. Therefore, a cradle to farm gate type
    Life cycle assessment (LCA) methodology has been used to quantify its impacts in terms of the chosen indicators. Taking
    one hectare of land under potato cultivation as the functional unit, the Sima Pro version 9.0.0 along with CML 2 baseline
    2000 approach have been used. The results highlight sowing and irrigation as the most critical processes that harm the
    environment. The findings of normalization results revealed that the marine aquatic ecotoxicity category was the greatest
    contributor to overall environmental impact. The results were further strengthened by substance contribution analysis
    which shows that carbon dioxide followed by nitrate emissions to air, water and soil was the most significant substances,
    accounting for 65.36% and 54.01% respectively.

  - RETURNS TO POTATO RESEARCH IN INDIA: A CASE OF KUFRI PUKHRAJ
    
    Authors: Narender Kumar Pandey, Sant Kumar
    Abstract: This study has estimated returns accrued from a potato variety called Kufri Pukhraj developed by ICAR-CPRI
    in 1998. This variety is most popular in North Indian Plains and covers about 33 % of total potato area in India. Timeseries
    data collated from published records have been used to assess benefits during the period 1978-2021. The economic
    surplus model is employed to measure benefits in a closed economy framework at all-India level. Results have shown that
    adoption of Kufri Pukhraj provided gross returns of Rs 1,03,585 crore during the period 1978-2021, and large benefits have
    gone to consumers (73 %) and remaining to producers. The average annual return was assessed as Rs 2,354 crore. The NPV
    from spending in potato research was observed Rs 20,073 crore, and Rs 7,975 crore at 5 % and 8 %, respectively, during
    the study period. The IRR from monetary benefits was 49 %, a good rate of returns. Sensitivity analyses have provided
    substantial returns, and IRR between 46-51 %. The study infers that spending on R&D on potato has proved financially
    beneficial and suggests that other major technologies (varieties/ production practices/ others) having special traits may be
    studied for justifying past funding and make the strong case for future funding.

    Authors: Boris Anisimov
    Abstract: The modern system of seed potato production and commercial quality control was developed by Russian
    Research Centre of Potatoes and approved further by Interstate Council for Standardization, Metrology and Certification.
    The major aspects concerning the common terminology, classification, specifications and methods for determining the
    quality adopted in Russia and unified with international systems and UNECE-Standard. In the present study minimum
    requirements for early generation seed production (original seed), further multiplication (elite seeds) and for end-use
    ware potato production (reproductive seed) is presented. Which includes: varietal identity and purity, diseases and pests,
    external tuber quality, sizing and labeling. The modern system of seed potato quality control includes field surveys during
    crop growth, post-harvest control (tuber analysis) and comparative field trial of seed potato samples. The major objective
    of comparative field trial in 2020-2021 crop seasons with the normative tolerances of the standard requirements related to
    varietal identity and purity and the level of viral and bacterial diseases transmitted through seed material. 288 samples
    of original seed potatoes were evaluated on the test-plot of the experimental base located at «Korenevo» of the Russian
    Research Centre of Potatoes (Moscow region) to determine their varietal identity, the presence or absence of other variants
    and plants affected by virus and bacterial diseases. Results of comparative field trial of original seed potato samples are
    considered in this article.
    Keywords: Articles ; EVALUATION OF POTATO VARIETIES FOR EXPORT POTENTIAL IN EARLY SEASON
    
    Authors: Pooja Praful Mankar
    Abstract: Uttar Pradesh, particularly its western region, has better export potential for the premium early potato segment
    as leading Indian exporters demand export-grade tubers (>55mm) during January to tap the deficit period of fresh potatoes
    in the global market. With this background, a field experiment was conducted during 2020-22 in the early crop season
    with five promising varieties/ advanced hybrid viz., Kufri Sangam, Kufri Kiran, Kufri Neelkanth, Kufri Chipsona-4 and
    WS/07-113. The crop was planted in September end and harvested in mid-January. Advanced hybrid WS/07-113 recorded
    the highest export-grade tuber yield (4.95 t/ha), followed by Kufri Kiran (4.63 t/ha). Maximum tuber dry matter content
    was attained by cv. Kufri Chipsona-4 (21.3%) followed by Kufri Kiran (20.1%) and Kufri Sangam (19.3%). As a specialty
    segment, exporters showed keen interest in cv. Kufri Neelkanth which has 4.32 t/ha export-grade tuber yield and 18.6%
    specific gravity. As exporters require potatoes in January, crop duration may easily be increased to 85-90 days to achieve
    higher yields. Performance of varieties and exporters’ feedback indicates that western UP can lead to export-grade potato
    production during the early-season.
